Much better than last year. But the pages slide badly -- need one page at a time to finish rather than slipping from page to page as I try to work on just one.

Getting to put 3 people on the account has been great. All of the features are exactly what I needed, and the editor is easy to use. I was a little wary if it would be worth the money, but I'm very happy with my purchase.

The go-to for creating useful PDF files This software has become a go to for pretty much every PDF file I have to create. I have used it to create forms that our midsize business uses on a daily basis. I find it to be very user friendly and a quick and easy way to get what you need. It has positively affected our costs of printing and paper, and it's good not only for our budget but for the environment too! Customer service is not the fastest and sometimes I have a question that needs to be resolved that day. I read online that it depends on the plan you have purchased and I don't think that is the best way to treat your customers.
